If you're looking to upgrade the performance of your braking, then a front brake kit upgrade is a great place to start. The front brakes do most of the work, since the front wheels cary the most weight, so you'll get the most bang for your buck just upgrading the front.

This kit includes high-carbon rotors for increased durability, with groves to help with removing the built up gasses and debris. The included pads are made to perform well up to 1300ºF to reduce the chance and severity of brake fade. Also included are stainless steel brake lines, which replace the stock rubber lines and give you a more responsive and stiffer braking feel.

Braking Parts Explained

Not sure how the braking system works on a car and what all the parts do? We prepared this quick explanation of all the components to help WRX drivers understand the details of how their braking system works.

Brake Rotors

Brake rotors are the circular piece that sits behind your wheel. When you press the brake pedal, the calipers clamp down on the rotor to slow the car.

Slotted Brake Rotor

Slotted brake rotors are designed with grooves to keep the system cooler under heavy repeated braking by increasing airflow. The slots also work to prevent debris and gas buildup between the pad and rotor.


Calipers are the part of the braking system that applies force to the rotor. Inside of the calipers are brake pads.

Brake Pad

Brake pads are the friction surface that sits inside of the caliper, and makes contact with the rotors. This friction forces the car to slow dow.

Brake Lines

Brake lines are hoses that connect to your calipers. When you press the brake pedal, hydraulic pressure travels through the brake lines to the capilers, causing them to clamp down.

Frequently Asked Questions

Have more questions about the Subaru WRX's brakes, or just braking systems in general?

How do you know if you need new brake pads?

Several common problems that are common when your brake pads in Subaru require replacement include cries of grinding, or squeaking when using the brakes. In cases of any of these warning indicators it's time to replace the brake pads, which can be a great time for an upgrade.

How long do brakes on a WRX last?

It entirely depends on your driving habits. Brakes can last for many years on a strictly street driven WRX, especially if you make sure to decelerate gently and use engine braking to help slow you down. It's also entirely possible to go through brake pads in just a few track days, if you're pushing the car to its limits for extended periods.

Can I put STI brakes on a WRX?

Yes, you can put STI brakes on a WRX. Keep in mind this depends on the model year of your car, as the parts might not fit on older WRX models. You'll need to check your fitment, and ensure you have enough clearance for the rotor to sit behind the wheel.
